A study was conducted by Esmeralda Farms researchers in their In Vitro Propagation laboratory to measure the effect of using AiroCide® PPT photocatalytic air purifying technology to kill airborne fungi and bacteria. 
Airborne levels of fungi and bacteria were measured in the laboratory chamber for 4 weeks prior to installing the AiroCide PPT air purifying system and for 4 weeks after installation. The size of the chamber was 96 m3 (approx. 3,400 ft3). 
The system reduced the amount of airborne fungi by 100% and reduced the amount of airborne bacteria by an average of 98% over the 8 week test period.
